We report a magnetic-resonance study of Gd-doped Eu2CuO4 single crystals. Cooling the samples in a magnetic field HFC, induces weak ferromagnetism (WF), with a strong out-of-plane anisotropy determined by the Dzyaloshinsky-Moriya (DM) interaction. In

We report the observation of an unusual electron spin resonance (ESR) signal in single crystals of Eu2CuO4. The signal appears to be associated with a resonance mode of the CuO2 planes, similar to the midfield and low-field absorptions we have report

We have measured the EPR spectrum of dilute Gd3+ ions substituting for Eu3+ in Eu2CuO4. Each one of the resonance lines shows a splitting into two or more weaker lines below TN 215 K. The simultaneous appearance of a low-field microwave-absorption si
